Probe type Tunable Diode Laser Spectrometer TDLS8100
Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000, but now only requiring a single-flange installation. An in-situ measurement with a probe still removes the requirement for sample extraction and conditioning and can be used in variety of aggressive process conditions.
The 0.5 meter measurement area of the probe provides some averaging improvement compared with traditional point-sensor technologies, and has flexible positioning of that measurement area with different insertion lengths being offered.
Built upon Yokogawa’s second generation of TDLS analyzers, the platform still retains its improved reliability, ease of installation, and reduced maintenance requirements, but now does so with lower total-installed cost for O2, CO, CO or CH4 measurements.
Features and Benefits
Reduced Installation and Maintenance Costs
- Single-flange installation eliminates the difficulties associated with aligning cross-duct solutions
- Measure in locations where cross-duct TDLS technology was not feasible due to obstructions or accessibility issues
- Easy installation with no sample system
- On-board diagnostics with 50 days of data and spectral storage ensure that minor issues can be identified before they become more serious problems
- Fully field repairable
- Explosionproof/flameproof for installation in CID1/Z1 or CID2/Z2 (when conbined with YH8000 Z2) areas
- No consumables are used which reduces equipment and time-related costs
- No re-calibration is required
- HART and Modbus TCP come standard to maximize remote diagnostics and configuration capabilities with a single cable run for each
- Manual, semi-automatic, or automatic validations can be performed to regularly test analyzer performance while on process
High Speed Accurate Measurement
- 2 second measurement update with as little as 1 second optional
- TruePeak technology keeps an accurate measurement, even when the process gas changes composition, temperature, pressure, or dust loading
- An in-situ probe eliminates sample lag introduced by comparable extractive technologies
Seamless User Interface
- Intuitive 7.5” touch-screen HMI configurable for 10 different languages
( Japanese, English, German, French, Spanish, Portuguese, Russian, Hungarian, Korean and Chinese ) - Intuitive operability
- Equipped with trend function, improved display function
- CID2/Z2 area rating on the HMI allows for local placement of the primary user interface in the majority of installation areas
- Installation of our free PC-HMI software duplicates the same user interface as the YH8000 HMI for more budget sensitive applications
TDLS8100 Probe type Tunable Diode Laser Spectrometer – flowcell type
For applications where the TDLS8000 or TDLS8100 could not be installed or inserted due to process size, etc., a sampling system can be constructed by replacing the probe part of the TDLS8100 with a flow cell part . Please contact Yokogawa.
System configuration
Standard system configuration
- Connectable with FieldMate or other DTM/DD compatible device management software using HART communication
- Mini Display
System configuration with remote YH8000 HMI
- Connect up to 4 analyzers simultaneously
- Can be used with the cross-duct TDLS8000 and/or the TDLS8100 probe
Measured gas
- O2, CO, CO or CH4
- Other near-infrared absorbing measurement gases may be available upon request
Structural Features
Easy installation reduces installation cost
Access on one side only
- No longer a maintenance scaffold needed on both sides
- No crossover wiring required for light launcher/ detector dedicated cable
Replace of extractive gas sampling analyzer
- Just replace gas sampling probe
- No expendable items such as filter, pump diaphragm
Long-term stable measurement
- Optical, hydrodynamics, thermal and vibration designed Probe to stabilize laser optical axis and optical path length for a long time
No light adjustment is required
- Since there is no light launcher side / light detector side, optical alignment is unnecessary
Robust and stable measurement realized
Resistant to vibration
- Even during vibration, various measurements enable laser light reception and achieve stable measurement
Features
Spectrum area method realizing high accuracy
In the conventional wavelength modulation method (2f method), the shape of the absorption peak and the height of the peak are affected by the interference gas. Yokogawa's proprietary spectral area method is virtually unaffected by the interference of other gases and can be measured with high accuracy by temperature and pressure correction.
High Reliability
Reference Cell
Internal reference cell in the laser module ensures peak locking during trace measurement.
Intuitive operability HMI YH8000
- Touch screen 7.5 inch color LCD on HMI
- Intuitive operability
- 10 languages display correspondence
( Japanese, English, German, French, Spanish, Portuguese, Russian, Hungarian, Korean and Chinese ) - Equipped with trend function, improved display function
- Up to 4 analyzers can be connected simultaneously
